Answer:
Answer is A. Two hydrogen atoms join together to form a molecule of hydrogen gas.
Explanation:
The electromagnetic attraction existing between hydrogen and other electronegative atom, such as nitrogen or oxygen, is known as hydrogen bond. It can also be explained as the electromagnetic attraction occurring when hydrogen binds to a higher or larger atom such as nitrogen.
Note that , the bond existing between two hydrogen atoms resulting in the formation of a molecule of hydrogen gas is covalent bond. Covalent bond can simply be explained as the sharing of electrons.
<span>The nurse should advice the parent on how they can quickly administer first aid because the distance between the home of the child and the hospital might be far and anything can happen before the child gets to the hospital for proper medical attention. Firstly, the parent should make sure that the item that might have lead to the poisoning far from the child and encourage the child to spit it out or have such items removed by using finger. The parent need to show the item to the doctors when she gets to the hospital so that the right diagnosis can be sort for immediately. The parent should however not force the child to vomit as this might lead to complications . If the child is not breathing the parent should patiently wait for emergency help from 911 to arrive</span>
Answer:
The answer is : Carbon catabolite repression
Explanation:
Carbon catabolite repression is a vital part of the global control system of the bacteria and other microorganisms. It allows the microorganisms to quickly adapt to the preferred energy and carbon source first. This is generally achieved by the inhibiting the synthesis of the enzymes that are involved in the catabolism of other carbon sources.
This effect was first shown to be initiated by glucose. Therefore, the carbon catabolite repression is also known as glucose effect.
Explanation:
The DNA contains many regulatory sequences that are very important, even though they do not code for proteins.
For example, the expression of every gene is regulated by a region called the Promoter. The promoter sequence, located close by the coding region of the gene, usually binds the RNA polymerase (the enzyme that transcribes genes into mRNA) as well as other proteins necessary for transcription,
The promoter sequence, thus, does not itself code for proteins, but is essential for transcription and must be highly conserved so that the RNA polymerase can find it.
Explanation:
All animals are in one kingdom (called Kingdom Animalia); all plants are in another (Kingdom Plantae). ... Other systems have six or more kingdoms. Species are the smallest groups. A species consists of all the animals of the same type, who are able to breed and produce young of the same kind.
